Debit Card Transactions
Debit transactions require integration to a PIN Pad that is injected with Elavon encryption keys to retrieve the following information:
- DUKPT Value: This is the value returned by the PIN Pad device which was used to encrypt the cardholder’s PIN, using the Derived Unique Key per Transaction (DUKPT) method.
- PIN Block: The encrypted PIN entered by the debit cardholder as identification for a transaction.
- Debit transactions may only be performed in a Retail, Service or face-to-face environment. Mail Order/Telephone Order and eCommerce businesses cannot perform online PIN-based debit transactions.
- Track II card swipe is required. Manual entry is not allowed.
